The Power Stroke is a really tall engine. You will need to build a new frame or stub to handle the weight of it.

The Crossmember on a Vic or even Aftermarket requires a short pan height.

As to re framing it, ask your DMV if it is legal to do this type of swap. The 61 to 66 F series VIN is dictated by the frame. Not the body. The warranty tag on your glove box door is not a VIN.

Plan ahead as to your goals and what you want the truck to do. Access your skill level and ascertain if you can even preform the work. If not be prepared to get expensive having a shop do it.
